I'm running Ubuntu 12.04 64bit on the Ivy Bridge Sony Vaio S. I installed bumblebee for nvidia-optimus support. Everything seemed to install fine, but if I use a command like: optirun firefox my computer just shuts down. No proper shutdown sequence or anything, just boom. down.
Any help would be very much appreciated.
